Angelopoulos et al., the teaching of which is incorporated herein by reference. FIELD OF THE INVENTION [0013] The present invention is directed to patterned electrically conducting polymers and methods of fabrication thereof. More particularly the present invention is directed to electronic devices having electrically conductive polymers as electrode contacts and active regions and patterned electrical contacts formed from electrically conductive polymers, in particular the application of these polymers as electrodes or electrical contacts for electrooptical transducers such as liquid crystal displays, electro-optical modulators, diodes, light emitting diodes, transistors, and the like. BACKGROUND [0014] The electrical contacts or electrodes in current electro-optical transducers and other devices are generally metals. Metals are deposited by evaporative or sputtering processes which require expensive tooling and overall are a cumbersome processes. [0015] Electrically conducting polymers are a relatively new class of electronic materials which are taught herein as candidates for electrode materials. These polymers combine the electrical properties of metals with the processing advantages of polymers. [0016] Herein we describe examples of electrically conductive polymers such as substituted and unsubstituted electrically conducting polyanilines, polyparaphenylenes, polyparapheylenevinylenes, polythiophenes, polyfurans, polypyrroles, polyselenophenes, polyisothianapthenes, polyphenylene sulfides, polyacetylenes, polypyridylvinylenes, polyazines, combinations thereof and blends thereof with other polymers and copolymers of the monomers thereof. [0017] In order for these polymers to be used as an electrode in a device they preferably have suitable electrical conductivity and be easily patternable. In addition, these polymers preferably do not outgas causing contamination of the devices to which they provide electrical contact. Furthermore, the conducting polymers are preferably patternable by lithography. Patterning preferably does not result in a decrease in the electrical conductivity of the polymer nor cause any deterioration of the properties of the electrically conducting polymer. [0018] It is therefore desirable to develop methods of patterning these polymers so that they can be used on any conducting polymer system and without negatively impacting the conducting polymer so that the patterned electrically conductive polymer can be used as an electrical contact to a device. It is also desirable that the conducting polymer properties be controlled so that outgassing or contamination of the devices does not occur. Objects [0019] It is an object of the present invention to provide improved electronic devices using electrically conductive polymers. [0020] It is an object of the present invention to provide patterns of electrically conductive polymers and methods of fabrication thereof. In particular, a resist is first patterned and the resist pattern is subsequently transferred to the conducting polymer. Once the pattern is transferred to the conducting polymer, the result is removed. [0021] It is an object of the present invention to provide patterns of electrically conductive polymers by the use of a resist which is applied to the conducting polymer. In particular, the metal is first patterned and the metal pattern is subsequently transferred to the conducting polymer followed by removal of the metal.
